Half of those were not putting him in danger and most of the others would be prevented by not going so fast. Bikers are so full of themselves. They like to speed and cut through traffic but if anything ever goes wrong it's the other guys fault. I see it all the time here, and the bikers are only justified maybe 1/3rd of the time at best, and that's being generous. I remember one fun memory where I was in traffic, I started switching lanes, had signal on, and then right as I started a biker came into view cutting between cars probably at least three times our speed. I stopped moving over to let him pass around me, but apparently that wasn't good enough and I should have completely returned to my lane so he wouldn't have to move slightly around me (and I mean less than a foot over, not half a lane or something). Anyways he flips me off and then gets in front of me and does hand gestures like teaching me to be in a lane and not on the line. Maybe he didn't see my signal cause he was going too fast? Anyways, he speeds back up cutting through cars ahead of me and guess what? Within like 4 cars he exact same thing happens to him again. And he got mad again. Hmm twice in a minute, maybe it's not us, maybe it's him! No, that can't be, bikers are perfect.
Its hard to say how much fault the biker had in this case because we don't see what started it. Could be the car was being reckless and the biker was justifiably upset, but it's just as likely that the biker overreacted from something harmless or of his own fault and provoked he rage. Not saying the car was justified in swerving to hit him, not at all, just that we don't know what actually upset the biker so much to start that shit.
Back to what I was saying earlier, hey bikers want to not die? Don't speed, cut lanes and pass between cars like you own the road. Don't blame us for not seeing you when your doing that shit, we don't have 360 vision, and we can only quickly check what's behind us not examine it with a fuckin microscope. Your much smaller than cars so your a lot harder to see, so if your cutting between cars, it's a lot easier to miss you. If you hit someone from behind, it's probably your fault for driving recklessly.
